2021-02-14net: dsa: tag_ocelot: avoid accessing ds->priv in ocelot_rcvVladimir Oltean
Taggers should be written to do something valid irrespective of the switch driver that they are attached to. This is even more true now, because since the introduction of the .change_tag_protocol method, a certain tagger is not necessarily strictly associated with a driver any longer, and I would like to be able to test all taggers with dsa_loop in the future. In the case of ocelot, it needs to move the classified VLAN from the DSA tag into the skb if the port is VLAN-aware. We can allow it to do that by looking at the dp->vlan_filtering property, no need to invoke structures which are specific to ocelot.

The felix DSA driver will inject some frames through register MMIO, same as ocelot switchdev currently does. So we need to be able to reuse the common code. Also create some shim definitions, since the DSA tagger can be compiled without support for the switch driver.

2021-02-14net: mscc: ocelot: only drain extraction queue on errorVladimir Oltean
It appears that the intention of this snippet of code is to not exit ocelot_xtr_irq_handler() while in the middle of extracting a frame. The problem in extracting it word by word is that future extraction attempts are really easy to get desynchronized, since the IRQ handler assumes that the first 16 bytes are the IFH, which give further information about the frame, such as frame length. But during normal operation, "err" will not be 0, but 4, set from here: for (i = 0; i < OCELOT_TAG_LEN / 4; i++) { err = ocelot_rx_frame_word(ocelot, grp, true, &ifh[i]); if (err != 4) break; } if (err != 4) break; In that case, draining the extraction queue is a no-op. So explicitly make this code execute only on negative err. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.

This is a new async message that the firmware can send to check if it can communicate with the driver. This is an added error detection scheme that firmware can use if it suspects errors in the PCIe interface. When the driver receives this async message, it will reply back echoing some data in the async message.

2021-02-14bnxt_en: Initialize "context kind" field for context memory blocks.Michael Chan
If firmware provides the offset to the "context kind" field of the relevant context memory blocks, we'll initialize just that field for each block instead of initializing all of context memory. Populate the bnxt_mem_init structure with the proper offset returned by firmware. If it is older firmware and the information is not available, we set the offset to an invalid value and fall back to the old behavior of initializing every byte. Otherwise, we initialize only the "context kind" byte at the offset. Reviewed-by: Edwin Peer <edwin.peer@broadcom.com> Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.

2021-02-14bnxt_en: Add context memory initialization infrastructure.Michael Chan
Currently, the driver calls memset() to set all relevant context memory used by the chip to the initial value. This can take many milliseconds with the potentially large number of context pages allocated for the chip. To make this faster, we only need to initialize the "context kind" field of each block of context memory. This patch sets up the infrastructure to do that with the bnxt_mem_init structure. In the next patch, we'll add the logic to obtain the offset of the "context kind" from the firmware. This patch is not changing the current behavior of calling memset() to initialize all relevant context memory.

2021-02-14bnxt_en: Implement faster recovery for firmware fatal error.Michael Chan
During some fatal firmware error conditions, the PCI config space register 0x2e which normally contains the subsystem ID will become 0xffff. This register will revert back to the normal value after the chip has completed core reset. If we detect this condition, we can poll this config register immediately for the value to revert. Because we use config read cycles to poll this register, there is no possibility of Master Abort if we happen to read it during core reset. This speeds up recovery significantly as we don't have to wait for the conservative min_time before polling MMIO to see if the firmware has come out of reset. As soon as this register changes value we can proceed to re-initialize the device.

2021-02-13Merge branch 'skbuff-introduce-skbuff_heads-bulking-and-reusing'David S. Miller
Alexander Lobakin says: ==================== skbuff: introduce skbuff_heads bulking and reusing Currently, all sorts of skb allocation always do allocate skbuff_heads one by one via kmem_cache_alloc(). On the other hand, we have percpu napi_alloc_cache to store skbuff_heads queued up for freeing and flush them by bulks. We can use this cache not only for bulk-wiping, but also to obtain heads for new skbs and avoid unconditional allocations, as well as for bulk-allocating (like XDP's cpumap code and veth driver already do). As this might affect latencies, cache pressure and lots of hardware and driver-dependent stuff, this new feature is mostly optional and can be issued via: - a new napi_build_skb() function (as a replacement for build_skb()); - existing {,__}napi_alloc_skb() and napi_get_frags() functions; - __alloc_skb() with passing SKB_ALLOC_NAPI in flags. iperf3 showed 35-70 Mbps bumps for both TCP and UDP while performing VLAN NAT on 1.2 GHz MIPS board. The boost is likely to be bigger on more powerful hosts and NICs with tens of Mpps. Note on skbuff_heads from distant slabs or pfmemalloc'ed slabs: - kmalloc()/kmem_cache_alloc() itself allows by default allocating memory from the remote nodes to defragment their slabs. This is controlled by sysctl, but according to this, skbuff_head from a remote node is an OK case; - The easiest way to check if the slab of skbuff_head is remote or pfmemalloc'ed is: if (!dev_page_is_reusable(virt_to_head_page(skb))) /* drop it */; ...*but*, regarding that most slabs are built of compound pages, virt_to_head_page() will hit unlikely-branch every single call. This check costed at least 20 Mbps in test scenarios and seems like it'd be better to _not_ do this. Since v5 [4]: - revert flags-to-bool conversion and simplify flags testing in __alloc_skb() (Alexander Duyck). Since v4 [3]: - rebase on top of net-next and address kernel build robot issue; - reorder checks a bit in __alloc_skb() to make new condition even more harmless. Since v3 [2]: - make the feature mostly optional, so driver developers could decide whether to use it or not (Paolo Abeni). This reuses the old flag for __alloc_skb() and introduces a new napi_build_skb(); - reduce bulk-allocation size from 32 to 16 elements (also Paolo). This equals to the value of XDP's devmap and veth batch processing (which were tested a lot) and should be sane enough; - don't waste cycles on explicit in_serving_softirq() check. Since v2 [1]: - also cover {,__}alloc_skb() and {,__}build_skb() cases (became handy after the changes that pass tiny skbs requests to kmalloc layer); - cover the cache with KASAN instrumentation (suggested by Eric Dumazet, help of Dmitry Vyukov); - completely drop redundant __kfree_skb_flush() (also Eric); - lots of code cleanups; - expand the commit message with NUMA and pfmemalloc points (Jakub). Since v1 [0]: - use one unified cache instead of two separate to greatly simplify the logics and reduce hotpath overhead (Edward Cree); - new: recycle also GRO_MERGED_FREE skbs instead of immediate freeing; - correct performance numbers after optimizations and performing lots of tests for different use cases.

Instead of just bulk-flushing skbuff_heads queued up through napi_consume_skb() or __kfree_skb_defer(), try to reuse them on allocation path. If the cache is empty on allocation, bulk-allocate the first 16 elements, which is more efficient than per-skb allocation. If the cache is full on freeing, bulk-wipe the second half of the cache (32 elements). This also includes custom KASAN poisoning/unpoisoning to be double sure there are no use-after-free cases. To not change current behaviour, introduce a new function, napi_build_skb(), to optionally use a new approach later in drivers. Note on selected bulk size, 16: - this equals to XDP_BULK_QUEUE_SIZE, DEV_MAP_BULK_SIZE and especially VETH_XDP_BATCH, which is also used to bulk-allocate skbuff_heads and was tested on powerful setups; - this also showed the best performance in the actual test series (from the array of {8, 16, 32}).
